Figure 1. Diagram by N. Hartsoeker (1694)
Diagram by N. Hartsoeker (1694) of how he imagined a sperm would look if it contained a preformed individual.
Hartsoeker later rejected the preformationist view, carrying out calculations of size that showed that if all of the animals of any species had been enclosed in the first male or female, those animals that now inhabit the earth would have to be infinitely and incomprehensively small.
